Title:
CONTROL SYSTEM FOR DOWNHILL WORKING CONDITION, AND ELEVATED WORK VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/051201
Kind Code:
A1
Abstract:
A control system for a downhill working condition, and an elevated work vehicle. The control system (1) comprises: a voltage measurement apparatus (10), which is used for measuring a direct-current bus voltage of a driver; a first current capture apparatus (20), which is used for capturing a feedback current delivered by the driver; a first switch apparatus (30), which is used for conducting a first circuit in which the first current capture apparatus (20) is located; and a control apparatus (40), which is used for conducting the first circuit by controlling the first switch apparatus (30) when the direct-current bus voltage is equal to or greater than a first preset voltage, such that the first current capture apparatus (20) captures the feedback current. The system can intervene in a control strategy to reduce a direct-current bus voltage of a driver by means of capturing a feedback current, so as to prevent the braking torque from becoming smaller, thereby effectively reducing the risk of downhill stalling.
